Final answer:
The correct sequence of photosynthesis steps: 1) Chlorophyll absorbs sunlight, 2) Water is split and oxygen is released, 3) Carbon dioxide and hydrogen produce glucose. This process generates the energy source for plants.
Step-by-step explanation:
The correct sequence of the steps of photosynthesis are:
- Chlorophyll absorbs energy from the Sun.
- Water is split into oxygen and hydrogen, and oxygen is released into the atmosphere.
- Sugar is produced from carbon dioxide and hydrogen.
Photosynthesis is the process where plants convert sunlight into chemical energy. It occurs in two main stages: the light-dependent reactions and the Calvin cycle. First, chlorophyll within the plant cells absorbs sunlight. The energy from this sunlight is then used to split water molecules into oxygen and hydrogen. Oxygen is released as a byproduct. Finally, in the Calvin cycle, the chemical energy derived from the light reactions, along with the hydrogen and carbon dioxide, is used to synthesize glucose, which acts as an energy soazor plants and other organisms.
